The thermal energy is provided by a 24 kW electric boiler, connected to a buffer storage to guarantee a quasi-constant inlet to the storage under testing. The charge is accomplished by directly connecting the storage under testing with the buffer. Instead, to obtain a settable discharging temperature, a motorised 3-way mixing valve (V3) and a plate heat exchanger (HEX2) are employed: in the HEX2, the water from the buffer is cooled down with tap water. By means of a PID algorithm, the 3-way valve controls the inlet to the storage under testing by mixing the streams from the buffer and the plate HEX. A bypass between inlet and outlet pipes that can be activated through manual deviating valves has also been installed to realise a pre-conditioning of the buffer. All the hydraulic pipes are thermally insulated. The management of the rig and the recording of the main parameters are implemented in a software realised in LabVIEW\u00ae environment. For the measure of temperatures, class A thermocouples are used, while a magnetic flow meter MagView MVM-040-PA with \u00b11% FS is used for the determination of the mass flow rate of the HTF.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-3670\" src=\"http:\/\/www.itae.cnr.it\/wp-content\/uploads\/2019\/03\/layout-rig-tes-1.png\" alt=\"layout rig tes\" width=\"700\" height=\"305\" srcset=\"https:\/\/www.itae.cnr.it\/wp-content\/uploads\/2019\/03\/layout-rig-tes-1.png 1293w, https:\/\/www.itae.cnr.it\/wp-content\/uploads\/2019\/03\/layout-rig-tes-1-300x131.png 300w, https:\/\/www.itae.cnr.it\/wp-content\/uploads\/2019\/03\/layout-rig-tes-1-768x335.png 768w, https:\/\/www.itae.cnr.it\/wp-content\/uploads\/2019\/03\/layout-rig-tes-1-1024x447.png 1024w, https:\/\/www.itae.cnr.it\/wp-content\/uploads\/2019\/03\/layout-rig-tes-1-600x262.png 600w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00a0 The testing rig available at CNR ITAE allows testing thermal energy storages employing PCM or hybrid latent\/sensible technology.
